Wife seeking Divorce

My marriage will complete 6 years in October. I am father of one baby girl. My marriage remained disturbed almost from the beginning. Reason behind is my in-laws. They always brain wash my wife against me. My in laws threatened me to kill multiple times & insulted me too beyond limits lots of time. This way I don't like them so I told my wife not to be in touch with them. But she always refused on this and left home multiple times for many months. Then I agreed with her that she only visit them but their involvement should not be in our family matters. But I saw it didn't happen and they kept on indirectly poking their nose in my life through my wife. Also, my wife without informing me meeting them, telling lie is on tip of her tongue. Every day without a miss in contact with her mother sharing all the secrets of my family, I would say I had no privacy in my life. These 6 years remained toughest in my life. Due to daily quarrels I decided not to expand my family, as I do not wanted tensions for our kid. But she kept pressurising me every time for the baby. But always I used to say no. Then I said her if you want to meet her parents then she can but she needs to promise me our kid will never meet them nor they meet my kid. At last she agreed on this and promised me too. But when my cute daughter came in my life after 3 & half years of marriage then my wife said that I did promise on that day now I won't agree with you. On this she left home along with my kid and now 2 years will complete on 24th of this October. In this time, I never met my daughter. Now, 2 days back she sent me sms to give her divorce and asked me if I want to settle divorce out of court or in court. She is working and earning more than me. My only aim is not to spoil my kids’ life. But wife's stand is like she wants divorce. I want we live together for our kid but don't want any involvement of in laws in any way as that will spoil our family mainly our kid. I just want to know if I had to give divorce, then how much right I have on my kid, what about maintenance and how much will be alimony. I earn 30k a month.
